ROBINSON, OF DETROIIIIIGHIGAN CORRELATING MEANS FOR CEILING oaranrrrron PANELS Application filed June 10,

V This invention relates to the structural association of plaster board or similar fiber partitioning panels which are now so much used for both wall and ceiling construction, and has for its object an improvedorganizw tion of parts by means of which the several sections of board which generaly come in stock sizes, and are designed to be positioned in the same plane with one another, may be firmly supported with relation to one another, and may have made strongly adherent thereto a coating or surface finish of plaster, stucco, or the like. By the use of my improved correlating means I am enabled to reduce to a minimum the appearance in the finished plaster surface of ridges, depressions, or cracks correspondingly positioned to the line of union between the plaster boards or panels, which is otherwise likely to occur because of the surfacing while plastic sinking more or less into the cracks or surface of the meeting edges of adjacent boards.

In the drawings:

Figure 1 is an elevational view of a ceiling structure wherein my invention is embodied, shown suspended as by means of wires from horizontal structural beams, whether wood or metal.

Figure 2 is an elevational view, partly in section showing my improved construction as applied to a wooden joist by nailing or similar means. Figure 3 is a perspective of my improved correlating means applied to fragmentary adjoining portions of two plaster board units. t

Figure 4 is a partly sectional elevational view thereof positioned in rather close relation beneath a structural beam.-

Figure 5 is a perspective similar to Figure 3, but showing the provision of structurally integral expanded metal flanges from the edges of the overbent sections of my improved correlating means, designed to constitute an additional adhering or binding means withoan applied coat of plaster.

Figure 6 is a sectional elevational v1ew taken along the line 55 of Figure 4, and

looking in the direction of the arrows there shown.- I Figure is a perspective similar to Figures 3 and. 5, but showing a slightly modified form of correlating web.

Figure 8 is a sectional elevational view taken along the line 88 of Figure 7 and o looking in the direction of shown.

At A in Figure 1 is shown a'horizontal the arrows there structural beam ofany' desired material,-

from the under side of which hang wires B, bymeans of which subordinate beams C are held in desired spaced relation from the main beam A. At intervals along the under side of the beam C are suspended channel bar elements D, or in place thereof, if de,

the wooden joist "E a' correlating sheet metal I web is secured thereto by nails H passing through the holes G1 f I As broughtout' particularly in the perspective figures, this correlating element, whethercorrugated or plain, is in the form of a central web J (or the plain web shown in Figure 7), from each of whose marginal edges as regards its vertically positioned section there project overbent flange pieces or sections, as M and N, with either'plain or serrated edges as indicated at T and V respectively, these being preferably spaced from one another and arranged in staggered relation, that is, for example, the overbent sections M not being positioned directly opposite the overbent sections N appurtenant the upper edge of the central web J. It will thus be obivous' that viewed lengthwise this flange pieces M and N aslmay overlapias regards their positioning lengthwise of the.

web piece asza whole thecross-sectional efiect would be zig-zagged in the shape of a more or and means for holding the panels and the inless right angled capital 2. The sheet metal terposed metal web in desired relative posistructure thus constituted is designed to have tion to a supporting element.

positioned, in the channels thus formed by its overbent edge sections M and N, the edges of panels or partition boards, as P and Q, which are thus firmly held in adjacent though not actually marginally contacting position, being spaced from one another by the web portion J (or K).

In some instances either the plain overbent sections such as are illustrated in Figure 7 or the corrugated overbent sections such asare illustrated in Figure 3, prone adequate to alone effect a binding interlock with an ap plied plasticcoating when the latter has dried. In other cases, however, I find it advisable to. provide extensions along the free or outer edges of the oyerbent marginal flanges in the form of an expanded metal edging unit such as is shown at L, and which it will be obvious will afford a greater surface for purposes of interlock with the plastic coating B when applied. a

It will thus beobvious that as to either of the forms of correlating member shown in Figures 3, 5, or 7, all preferably of sheet metal of appropriate gauge, there is not only constituted an efiicient mechanical union of as many panels as may be needed, but that the space between each, in which the central web of the correlating member lies, is so protected and filled, not only by it butby the overengagement onto the marginal edges of the surface of these panels, of the oyerbent sections, as M and N, that very little of an applied plastic coating, as R, can sink thereinto and thus form troughs or cracks or depressions inthe hardened, finished surface thereof. Such of the plastic coating as may make its way into the web-occupied. space be,

tween the edges of adjacent, boards, particularlyiif the central web portion is of the corrugated character indicated. at J in-Figure 3, tends to form, when hardened, key projections, of course integral with the rest of the plaster body, which actually strengthen and increase the degree of the hold of the latter upon the built up and correlated base structure herein described.

What I claim is: I

Means for eifeeting-the aligned correlation of partitioning panels and for facilitating; the. adherence thereto. of an applied: plastic coating, comprisinga plurally crenelated;

sheet metal Web having alternately right-angularly over-bent portions adapted-to overengage the marginal edge of one surface or the other of a panelwhose'bordering edge is, placed against the central; part of the web,

structurallyintegral; extensions from. said overbent port-ions having slitted portions, between and' about which an applied plastic surfacingmay efi'ect a space filling and; sue

'perficially straight interlock when, hardened,
